    <ListBox.ItemContainerStyle>
        <Style TargetType="{x:Type ListBoxItem}">
            <Setter Property="Template"> 
                <Setter.Value> 
                    <ControlTemplate TargetType="{x:Type ListBoxItem}"> 
                        <ContentPresenter /> 
                    </ControlTemplate> 
                </Setter.Value> 
            </Setter>
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox>

Answer 1

Can you style the item template of the listbox and put a textblock in there, then use it’s tooltip property?

<ListBox ItemsSource="{Binding Strings}">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding}" ToolTip="Here is a tooltip"/>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>
